The SSM mounts directly to your rifle sling swivel stud. One end of the SSM can be mounted to any switcheroo compatible BOG-POD. The other end is a sling swivel stud, allowing you to mount your sling while the SSM is attached. Once the SSM is mounted to a BOG-POD it will stay mounted even if you pick up your rifle. The POD and SSM will not detach. Now you can move your rifle, POD attached, for quick target re-acquisition.
